- Primary Outcome Measures
Name Time Method Time to Relapse Weeks 0 - 24 of study participation Time to relapse defined as time until psychiatric rehospitalization during the study period
- Secondary Outcome Measures
Name Time Method Hamilton Depression Rating Scale Weeks 0 - 24 of study participation The Hamilton Depression Rating Scale (HAM-D) will be used to measure depression-related symptoms. The HAM-D contains 24 items, each rated either on a scale from 0 to 2 or on a scale from 0 to 4. Total scores range from 0 to 76, and higher scores indicate increased depression-related symptomatology.
Young Mania Rating Scale Weeks 0 - 24 of study participation The Young Mania Rating Scale (YMRS) will be used to measure mania-related symptoms. The YMRS contains 11 items, each rated either on a scale from 0 to 4 or a scale from 0 to 8. Total scores range from 0 to 60, and higher scores indicate increased mania-related symptomatology.
Columbia-Suicide Severity Rating Scale Weeks 0 - 24 of study participation The Columbia-Suicide Severity Rating Scale (C-SSRS) measures suicide attempts and ideation. The C-SSRS is a tool containing one section of items used for assessing the specific type and intensity of suicidal ideation and one section of items used to determine number and type of suicide attempts and actual or potential lethality of the most lethal suicide attempt. The number of items used depends upon participant responses, and higher ratings on specific items indicate either more attempts, more intense ideation, or more lethal behavior. The C-SSRS will be used to determine the occurrence of suicide attempts or ideation.
Brief Psychiatric Rating Scale Weeks 0 - 24 of study participation The Brief Psychiatric Rating Scale (BPRS) will be used to measure the severity of psychiatric symptoms. The BPRS contains 24 items, each rated on a scale from 1 (not present) to 7 (very severe). Total scores range from 24 to 168, and high scores indicate increased symptomatology.
Montgomery-Åsberg Depression Rating Scale (MADRS) Weeks 0 - 24 of study participation The Montgomery-Åsberg Depression Rating Scale (MADRS) will be used to measure depression-related symptoms. The MADRS contains 10 items, each rated on a scale from 0 (none or normal) to 6 (most severe). Total scores range from 0 to 60, and higher scores indicate increased depression-related symptomatology.
New Mood Episodes Weeks 0 - 24 of study participation Number of new mood episodes determined by Structured Clinical Interview for DSM-5 Disorders (SCID-5), an interview using criteria from the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5)
